They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Answer:
B:subtraction property
Step-by-step explanation:
The slope is the coefficient of x when the coefficient of y is 1.
The slope is -0.5
The y-intercept is where x=0
y = 17 - 0.5 (0)
y = 17
The y-intercept is 17.
You substitute the y from the second eqaution to the y in the first equation
